![]() ![]() ![]() PWPS a set of written instructions for welders that reveals how should be the production of weld made. Welding Procedure Specification is divided into two types. It makes sure that welders can produce quality welds.The WPS explains to engineers and regulators what you are doing on a piece of metal.The procedure is necessary and required by codes such as AWS and ASME.We need a welding procedure specification for welders in the industry for the following reasons. Look at what two highly popular welding bodies in the USA say about the WPS requirement.Īmerican Welding Society (AWS) defines WPS as essential welding variables for a specific application.Īmerican Society of Mechanical Engineers (ASME) defines WPS as a written document providing guidelines to welders and welding operators for performing welding production as per welding codes. The document mainly suggests welders for accepting it and follow the trusted/proven welding codes and techniques. WPS is a document consisting of welding procedures and guidelines for welders and welding operators. What is the Welding Procedure Specification? What is the Welding Procedure Specification?.It explains a prescribed description of the welding process, gases and flow rates, the joint design and geometry, the base materials used, welding position including various variables. Welding Procedure Specification (WPS) is a written and detailed document for welding operations. ![]()
